Steve, I agree with you, all that must be done and has been done AHEAD OF TIME.
So, let's put everything together now... AHEAD OF TIME:
My Sampling plan is based on ISO2859 and defines:
a. Acceptance Criteria: 2,3 (Acc,Rej) (=Given as result of LOT size and AQL)
b. Defect Class: Minor
c. Number of Characteristics to check: 3
d. It takes 1 characteristic - no matter which one - for a unit to count as defective.
And here are the results of the inspection:
Sample 1 is defective (fails on Characteristic 1)
Sample 2 is defective (fails on Characteristic 1)
Sample 3 is defective (fails on Characteristic 2)
Now I need your help to count the defect units:
METHOD A: I count 3 defective units in total ==> LOT REJECTED
METHOD B: I have 2 defective units for Characteristic 1 and 1 defective unit for characteristric 2. The maximun number of defective units for all characteristics under inspection is 2 ==> LOT ACCEPTED
Which is the correct method to count the defect units in your opinion?
